Question:

CS Extension/CS Mets: For primary sites within the peritoneum (abdominalpelvic walls) such as stomach, colon, does the presence of malignant ascites affect the coding of CS Extension or CS Mets?

Discussion:

Answer:

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.

The Collaborative Staging system is governed by site-specific coding rules. Refer to each set of site rules rather than looking for a general answer for all sites in peritoneum. In particular, Ovary and Corpus allow malignant ascites to be coded in CS Extension, but not CS Mets at Dx. For each site, both CS Extension and CS Mets at Dx should be checked for the proper field to code malignant ascites.
